The private certificates that sign our binaries are tightly controlled and not accessible to our servers or our GitHub accounts, so the scenario you're describing could only happen if an attacker compromised our Github account
and our private signing certs (gaining access to our back end servers wouldn't help an attacker at all).
Of course, no system is invulnerable to any attack. But in practice, Doppler's architecture implies a much larger degree of trust (any server breach = secrets compromised) than EnvKey's (servers can be fully breached and secrets still aren't compromised). Doppler looks like a great product in many other ways, but I do think it's important for users to fully understand the risks they're taking.
